Label A Smaller Child - Lower Marker 
A Child who has outgrown their child restraint with in-built harness will have their shoulders 
in line or above the lowest shoulder height marker (label A) of this booster seat with the 
headrest in the lowest 
position. If the child’s 
shoulders are below 
this marker the child 
needs to stay in their 
child restraint with an 
in-built harness.
Label B Larger Child - Upper Marker
The seat can be used until the child’s shoulders reach the Upper Marker (label B) with the 
headrest fully raised. Usually the shoulders will contact the bottom of the headrest, it is 
then time to move 
to the next form of 
restraint.
For maximum safety 
continue to use this 
seat as long as the 
child ts in the seat.
